INVENTOR fl Bery mph '0 ATTORNEY m [40 vertible door NI ED STA AIirnEn-n'nnnnizsrimn,for AnsnvG, ANSAS; L

To all whom it may comma? 7 v Beit known that I, ALFRED E. DERBY-- si-imna citizen of the United Statesyr'es'iding at Lansing, in the county 'of ,Le'aVen-i worth and State of Kansas',*have invented ner topermit of its being entirely moved to one. side after the manner of the ordinary l5 sliding doors of freight cars.

The primary object of the invention is the construction of a door as above set forth which will prevent the loss of the same by being blown from the car, or from side swiping orany other accidental or unauthorized removal.

. A further object of the invention is to pro- 1 vide a door which will resist the pressure of grain or other freight or commodities being handled, the door also being constructed I a manner to render it water proof.

A still further object of the invention is the provision of a door in which the sections,

willbe automatically opened and held in either open or closed position, thereby facilitating the handling of freight andfobviating the annoyances incident to sections accidentally falling from theiradjusted positions.

The construction above described will eliminate the necessity of temporary wooden grain doors such as now in general use and "when applied in sections to the side of the car may be used. for the purpose of a con;

for the handling of general freight. H V

With the above and other objects in view the invention consists of the following novel combination and arrangementof parts, here-.

inafter morefully described, illustrated in the accompanying drawings; in which-- 7 tion of a freight car having the improved door applied thereto;

Fig; 3 is a vertical central sectional view through the door;

Fig, i is a horizontal sectional view" through the upper section, the sliding frame, f

as and thedoor r m Specification oflietfters l atent.

Fig. 2 is an inslde elevation of the same; 7

'iReferring to the drawings'in detail the i '1 '7 side ofthei car is designatedat 'A, and 'the bottom'at B. 7' The car herein shown is of the is detailed view-"illustratingthe glnanner of holding theupp' rsection in posimetaltype and consists bfan outercasing and-an'innersealing or lining 1C.

The improved door includes the slidi ig frame 10, which is adapted tooperate within a groove 11 provided over the upper portion of the dooropening. The lower'partof this frame is provided with rollers"'1'2,fwhich are adapted to operate in afgroove' 13 formed in" the-sill or i-threshold' of'the door. The

grooves 11 and 13 extend within the pocket formedby the side of'the car A and the lini moved entirely to one side the pocket is formed with a groove '14 t o1reframe of the car when the same is closed.

ing C, inorderthatfthle frame 10 ma y be v of-the door open 7 ing; The edge of the door opening opposite The'sliding frame 10 is provided with vii-j Qticall side parting beads 15 and l6, for thepurpose of separating upper and lower sections 17and18 respectively;- These sectionsv are provided with rollers 19 to The scctions l'i and 18' are adaptedto provide for the said sections being provided with inturned edges 22 which act with the grooves i v 20 and 21 to-serveto prevent the entrance of theweatherf within the car. The upper section 17 isprovided with a spring arm 23, i the saidarrn being slightlyoflset from the basesectionand having'its free "end formed with ;an inturne'd "portion 024, which is adapted to engage the upper edge-22 of the Figure 1 is an outside elevation of aporsectionl8 and act to hold the'said sectionv infits lower or closed position. The-said section" 18 carries a lug 25, when the section is raised is adapted to engage the 1 portion 2401? the spring arm-'23 and hold the section; in i1ts raised, or ope'n position,

For the, purpose of holdingthe section 17 I 2 top of: the fr'ame -1O is providjed;w1th. a

grooved latch 26, the said latch being located in the path of the'spring arm 23'and being provided with a beveled head 27, so

that when engaged by the arm 23 it will be forced to one side to permit the passage of the same. After the arm 23 has passed a sufficient distance the latch 26 will swing irto the path of the arm and hold the section 1 up.

The frame 10 is provided with a handle 28 by means of which it is moved to open or close the door, the said handle also acting as a stop to the outward movement of the said door. The lug 25 also provides aconvenient .means for prying the door open should the force ofthe grain or other material within the car resistsuch opening. The sill or threshold of thedoor, in which is formed the groove 13, is beveled as shown to facilitate the loading and unloading of the car.

From the foregoing description when taken in. connection with the accompanying drawings, it Will be seen that the invention provides a convenient and easily operated weather vproof .door, which may be used either for the hadling of grain or ordinary freight. It will also be seen that the construction of the door is of a simple character, thereby, insuring its easy and positive operation.

Any suitable means may be provided for sealing the door.

Having described the invention, what I claim is:

A car door comprising a horizontally sliding frame, a door mounted for vertical sliding movement therein, said door including upper and lower sections, a vertically disposedspring arm having one end secured near the upper edge of the upper section and its lower end formed With an inturned extremity for engagement with the upper edge of the lower section when the latter is closed and a lug carried by the lower section and adaptedtotengage the inturned extremity of the spring arm to hold the lower section open.

In testimony whereof I affiX my signature.
